摘　　要：目的了解宁夏人群土源性线虫(蛔虫、鞭虫、钩虫和蛲虫)感染现状。方法采用整群随机抽样方法,抽取46个调查点,对调查对象采用改良加藤厚涂片法检查粪便中蛔虫虫卵、鞭虫虫卵、蛲虫虫卵,对3～14岁儿童采用透明纸肛拭法检测蛲虫虫卵。结果共调查34 023人,土源性线虫总感染率3.40%。其中镜检粪便30 241份,检出2种土源性线虫(蛔虫、鞭虫),未检出钩虫。蛔虫感染率3.49%,地区间感染率差异有统计学意义(χ2=3784.63,P<0.01),5～9岁组感染率显著高于其他年龄组(χ2=108.46,P<0.01),男女性别间感染率差异无统计学意义(χ2=0.05,P>0.01);鞭虫感染率0.29%;儿童蛲虫感染率2.69%。结论今后仍需加强对南部山区等高感染地区,尤其是14岁以下儿童及农民等重点人群的土源性线虫病综合防控工作,进一步降低感染率。Objective To understand current crowd geohelminthes （roundworm, whipworm, hookworm and pinworm） infection status in Ningxia,and to provide a scientific basis for the future focus on prevention and control work. Methods The stratified cluster random sampling method was used for survey ,46 survey points were selected in 2011, survey Kato - Katz thick smear method for detecting ascaris eggs in faeces, whip worm eggs, pinworm eggs, cellophane anal swab method to detect pinworm eggs for children 3 to 14 years. Results A total of 34,023 people were investigated, soil -transmitted nematodes total infection rate of 3.40%. Among them, 30,241 copies stool were detected by microscopic examination, the detection of two kinds of soil - transmitted nematode （ roundworm, whipworm） ,were not detected in the hookworm. Roundworm infection rate of 3.49%, there were significant differences about the infection rate between regions （X2 = 3784.63 ,P 〈 0.05 ）, the infection rate in 5 to 9 -year- old group was significantly higher than other age groups （ X2 = 108.46 ,P 〈 0.05 ） ; whipworm infection rate of 0.29% ; children pinworm infection rate of 2.69%. Conclusion Need to be strengthened soil - borne worm disease prevention and control work in high - infection areas of the southern mountain in the future, especially under the age of 14 children,farmers and other key groups,to further reduce the infection rate.
